6.3 Camera Block Diagram
Fig. 1.1 VH (Camera Link) Series Camera Block Diagram
Fig. 1.2 VH (GigE) Series Camera Block Diagram
All control and data processing of VH cameras are carried out i n one FPGA chip. The FPGA has a 32 bit RICS
microprocessor with processing & control logic. The microproces sor processes commands from the user through
the Camera Link interface. The FPGA controls the AFE (Analog Front En d) chips that con verts the pixel values in
the ADC (Analog Digital Convertor) to digital. The FPGA provides the timing to the CCD through the Timing
Generator. Im age data received through AFE, is proc essed by the FPGA and sent to through t he CameraLink
interface. The FPGA receives the trigger input and generates the s trobe output, mak ing sure the latency is very
low. SDRAM is used for image frame buffering and FLASH contains the firmware that is used to operate the
micro-controller.

6.4 Sensor Information
Camera uses Kodak CCD as image sensor. After exposure for certain period of time, the electric charges
accumulated on each pixel of CCD move to Vertical Register (VCCD) by control signal and then to Horizontal
Register (HCCD) by vertical cont ro l s ignal, li ne by line. Electric char ges acc umulated on HCCD are sent after being
converted to voltage value for eac h pix e l b y horizontal control signal. At this time, it can be s im ultaneous l y out put to
single direction (Video L) or both directions (Video L and Video R) depending on horizontal signal approved.

7.1 Area Of Interest (AOI)
AOI is th e area containing the data required by the user within the entire image. The us er can obtain the image
faster with the same high quality as when obtaining overall areas by designating the area as AOI. AOI is
determined as the ov erla pp ing ar ea of 2 areas when designating Start point and End p oin t i n hor i zontal a nd v ertic al
directions as shown in Fig 3.1. Start point and End point mean the starting and end of the AOI. The narrower
Vertical AOI gets, the faster the frame speed. But Horizontal AOI does not affect frame speed.

7.2 Binning
Binning has the effect of increas ing the av ailable pix el well c apacity and dec reasi ng resolut ion by ad ding the value
of an adj acent pixel and se nding them as one pixel. The cam era applies the same Binning Factor (2 or 4) to both
directions in order to maintain the as pect ratio of the f ull resolution image. Fig 2.8 and Fig 2.9 show application of
2x2 Binning and 4x 4 Binning, respectively. Since Binning in the vertica l direction is processed within the shielded
vertical registers of the CCD, the frame speed increases by the Binning Factor approximately (2X or 4X).
Binning in the horizontal direction does not affect frame speed. Binning Factor is set using the “sbf” command.

7.3 Exposure
Exposure time of camera is adjuste d by shutter signal. S hutter signal is the signal that r em oves the elec tric c harge
accumulated on CCD pixel until shutter signal is generated, and accumulates the electric charge thereafter.
Therefore, Exposure Time of cam era is determined at the inter val between shutter signal and VCCD signal. Since
actual VCCD signal consists of 2 level wa veforms as shown in the following Fig. 2.10, Exposure Time is th e time
from downward edge of Shutter signal to high level downward edge of VCCD signal.

“set” command is used to set Exposure Time. (See 4.4 Exposure Time). Available minimum value is 10us and
maxim value can b e set up to 7s. Ho wever, it should be noted that Exposure Time set with “set” command is the
time from starting point of shutter signal to s tarting point of VCCD signal, and slightl y differs from Exposure Time
actually applied. As shown in Fig. 2.10, relation between exposure time set and that actually applied are as follows:
Actual Exposure Time = Programmed Exposure Time + T3p + Tv3rd – Tsh
Since T3p, Tv3rd and Tsh are the factors determined by CCD used, difference between Exposur e Time actually
applied and Exposure Time set in advance differs depending on camera model.
See following Table 2.3 for T sh, T3p, Tv3rd for each model.

7.4 Trigger
7.4.1 Trigger Input
2 kinds of sources can be used as trigger input: CC1 port (CC1+, CC1-) of Camera Link interface and
TRIGGER_IN port (TRIGGER_IN+, TRIGGER_IN-) of power connector. TRIGGER_IN port is separated from inside
of camera by Opto Co upler and has 470 O hm resistance inside to restrict the current. TRIGGER signal is us ed
inside FPGA through Inverting.

7.4.2 Trigger Mode
Trigger modes can be divided into s ynchro nous and as ynchronous trigger ing (“Fr ee-Run mode”) depending on the
mode selected. The synchronous triggering modes are Standard, Double Exposure, Fast, an d Overlap modes.
The asynchronous triggering mode is Free-Run mode.
The Trigger Mode can be set to a s ynchrono us m ode t hroug h the CC1 port (seria l port) . For low latenc y (m inim al
delay), the externa l TRIGG ER_IN p ort shoul d be used as tr igger inp ut. The trigger polarity can be set Positi ve or
Negative by serial commands or reversing the external TRIGGER_IN leads.
7.4.2.1 Free-Run Mode
Free-Run Mode will continiously be reading images based on the camera’s settings regardless if there is
a trigger input.

Fig. 2.15 Free-Run Mode
As shown in Fig 2.15, the readout sect ion overlaps with the exposure sectio n of the next im age. This is Free-Run
Mode. At this time, camera operatio n slightly differs depending on length of Exposure Time and Readout ti me. If
Exposure Time is shorter than Readout, Shutter signal occurs during readout, and when Readout finishes, Readout
of the next image s tarts. (Fig 2.16) In this cas e, frame speed is cons tant regardless of change in Exposur e Time.
But if Exposure Time is set longer than Readout time, the Shutter signal will occur at the start of the image Readout.
Readout of the next image does not start until the Exp os ur e Time is f in is hed , even if Readout f in ishes . (Fig 2.17) In
this case, frame speed is reduced as the Exposure Time increases.

7.4.2.2 Standard Mode
In Standard Mode, camera keeps standby status until trigger signal is entered, and when trigger input occurs,
Readout start after Exposure process set earlier. After Readout is completed, camera operation slightly differs
depending on Frame Number setting. Frame Number can be set as the value between 0~255. If it is set to 0,
camera converts th e operation m ode to Free-Run mode, instead of returning t o trigger standb y status. If it is set to
1, it returns to trigger standby status. If it is set to t he value of 2~255, it repeats Readout in Free-Run mode as
many as the number less than 1 from the number set, and returns to trigger standby status again. “sfn” command is
used to set Frame Number. (See 4.6.3 Frame Number)

7.4.2.3 Double Exposure
In Do uble Exposur e mode, 2 im ages are obtained wit h 1 trigger input. When trigger input is en tered in this m ode,
the camera starts Readout after passing thro ugh exposure process acc ording to exposure s etting as in Standard
mode. At this time, exposure of second image starts with Readout. When Readout is completed, the camera
performs the second Readout.
In Dou ble Exposure mode, it acts sim ilarly as the case when Frame Number setting is 2 in Standard mode, bu t
differs in that shutter signal occur s at least once. Therefore, when Frame Number setting of s tandard mode is 2,
exposure time set in cam era is app lied in s econd image, while exp osure tim e of second im age in Dou ble Ex pos ure
mode coincides with t he Readout of 1
st
im age. Since it d oes not generate shutter signal during Readout of the 1st
image, the interval b et ween c ompletion of 1
st
exposure and starting of 2nd exposure is as shor t as s ever al u s ~ tens
of us.

7.4.2.4 Fast Mode
Fast Mode is used when interval of trigger input is faster and more continuous than in Standard Mode. Its difference
from Standard Mode is that while Readout starts in exposure time as set earlier when trigger input occurs in
Standard Mode, while Readout immediatel y starts after trigger input in Fast Mode. And Interv al between triggers
becomes the exposure time of image since it does not generate shutter signal during Readout.

7.4.2.5 Overlap Mode
Camera keeps standby status until trigger signal is entered like in Standard Mode, and Readout starts
after exposure process set earlier if trigger input occurs. When new trigger input occurs during Readout
of First image, it keeps Readout and pass exposure process of new trigger input. Provided, however, that
when trigger input occurs during Exposure since Exposure Time is longer than trigger interval, that
trigger signal is ignored. To obtain the image as maximum frame for trigger input, Exposure Time should
not be longer than Readout time, trigger time should not be shorter than Readout time. Readout time for
each model is as follows:
VH-310G-72 VH-310G-264 VH-2MG VH-4MG VH-11MG VH-16MG
Readout Time 13.8ms 3.8ms 23.8ms 49.7ms 149.9ms 250ms
In addition, overlap mode operates ideally when trigger signal interval or exposure time is constantly
kept.

7.4.3 Asynchronous Reset
If new trigger is enter ed in camera in tr igger mode status duri ng Readout due to generation of trigger input, it can
be set to stop previous Readout process, to execute Exposure and Readout process for new trigger input, to ignore
newly entered trigger and to continue previo us Readout. This s etting is called Async R eset, and the form er is the
case of activating As ync Reset and the latter is the case of inactivating it. “sar” command is used for Async Reset
setting.(See 4.6.6 Asynchronous Reset)

7.5 Channel Mode
When reading data from Horizontal Register of CCD, it can read in Single Channel or Dual Chann el. In case of
single channel output, all pixel values of Hor izontal Register come thr ough left Video Amplif ier(Video L). In cas e of
dual channel output , pixel values left to t he c e nter of H or i zontal Register com e through Video L, and pixe l va l ues to
the right come through Video R. Since output to dual channe l is carried out at the same time, the frame speed
increases about 2 times than the case of single channel.

7.8 Defective Pixel Correction
There is Defective Pixel in CCD, which cannot properly react to the right. Correction is required since it may
deteriorate the qua lity of output image. Defective Pixe l information of CCD use d for each cam era is enter ed in the
camera at the phase of forwarding from the factory. If the user wants to add Defective Pixel information, it is
required to enter c oordinate of new Def ective Pixe l in camera. See
Appendix A f or details. “sdc” command is used
to set whether to use Defective Pixel Correction function (See 4.11 Defect Correction)
7.8.1 Correction Method
Correction value of Defective Pixel is calculated based on valid pixel value adjacent in the same line.

7.15 Strobe
Strobe signal is used to measure the exposure time to synchrnoize the external light source with camera or to
measure the exposure time applied to current camera. Pulse width of Strobe signal is from the generating point of
Shutter signal to the starting point of Readout, which coincides with exposure time of camera.

8. Camera Configuration
8.1 Setting Command
All settings of camera are carried out thr ough serial interface of Cam era Link. All commands f or camera setting
except commands (Firmware, LUT, Defect, etc.) requiring tr ansm is sion of m assive data are de livere d in the f orm of
ASCII command. All commands for camera setting start from user application and the camera returns the
Response (“OK”, “Error” or information) for commands. With write command, the camera informs whether
command is successfully executed through response. W ith read command, the camer a returns error response or
information.
UART Setting
- Baudrate : 19200 bps
- Databit : 8 bit
- Parity bit : none
- Stop bit : 1
- Flow control : none
Command Format:
<command> <Parameter 1> <Parameter 2> <cr> command follows 0~2 parameters.
Response:
- Execution of write command is successfully completed
OK <cr> <lf>
- Execution of read command is successfully completed

8.2 Parameter Storage Spaces
Camera has 3 non-volatile stor age space used for saving param eter, and 1 volatile work s pace applied to actual
operation of cam era. 3 storage spaces are Factory Space that contains the default at the tim e of forwarding from
the factory; 2 user spac es (User Space 1, User Space 2) that sav e parameter values randomly set b y the user.
Both write and read are possible in user space, but only read is possible in Factory space.
Depending on Conf ig Initiali zation value at t he time of camera bootin g, setting va lue at one of 3 storage spaces is
copied to work space, and the value in this space is u sed for camera setting. Since the value in the work space is
valid only when the po wer is on, it is required to cop y it to user space 1 or user space 2 using “sct” command in
order to use this value again. (See 4.18.1.4 Save Config To)
